Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Effect of priming on seed quality in pigeonpea. (Cajanus cajan L. millsp.)
    (CCSHAU, 2006) Ashok Kumar; Kashyap, R.K.
    Experiment was conducted to study the effect of priming on seed quality in pigeonpea and also to study the various enzyme activities. To undertake this study two improved variety viz. Manak and Paras were studied. Each variety was grouped into two seed lots on the basis of germination i.e. L1 good seed lot L2 marginal seed lot. It was observed that marginal seed lot L2 performed better after applying pre-sowing treatments under laboratory and field condition. And among varieties, Paras performed better in field condition than Manak in all the priming treatments. Among all the treatment only GA3 (50ppm), cold hydration and cold dehydration +0.25% thiram showed positive results in both the varieties and lots. Treatment cold dehydration +0.25% thiram showed highest improvement in germination, vigour index-I, plumule length and dry weight in both the seed lots. An effort was also made to enhance the germination of marginal seed lot by applying CaCl2 and KNO3 priming treatments but the experiment showed negative results in both the treatments in pigeonpea. It was revealed that variety Manak was showed good enzyme activities than the Paras. And among seed lots lot L1 showed good enzyme activities than lot L2.

    Epidemiology and management of anthracnose of chilli (Capsicum annuum) caused by colletotrichum capsici (Sydow) butler and bisby
    (CCSHAU, 2008) Ashok Kumar; Khirbat, S. K.
    Studies on epidemiology and disease management were carried out with Colletotrichum capsici causing anthracnose of chilli. Emphasis was on the initiation and progression of the disease in relation to the weather variables. The present study revealed that the disease development was maximum when the temperature and relative humidity were 300C and 100 percent, respectively in vitro. In host range studies, the pathogen infected three crops (mungbean, soybean and bottlegourd) and three weeds (kondhra, chilmil and santhi). Relationship has also been worked out on spore population, weather parameters and disease development. Disease development was directly proportional to the spore production in the field. Further, temperature (maximum) in the range of 30.60- 35.900C, temperature (minimum) 21.70-26.500C, relative humidity (morning) 84.30- 97.00 percent and relative humidity (evening) 54.30-58.30 percent were congenial for disease development. The regression coefficient of the disease severity and spore population with weather parameters revealed that temperature (minimum) and temperature (maximum) played major role which could predict 85 percent of disease severity and 54 percent of the spore population, respectively. Colletotrichum capsici was more sensitive to Bavistin which gave complete inhibition of growth at 250 ppm concentration in vitro. Among the four plant extracts Datura species gave 100 percent spore germination inhibition which was at par with mancozeb at 0.1% concentration.
